City of Lincoln Council Leader Ric Metcalfe said: “This is essential exploratory work looking at the condition of these former landfill sites. When we know what the options are we can consider the best way forward to help us achieve our aims.

“Growth is essential to ensure Lincoln’s future, and the Western Growth Corridor is the biggest and most sustainable site we have to enable us to provide homes, jobs and services for a growing population.

“Any development would need to be safe and appropriate, which is why we are carrying out this investigative work.”
